It is better than the "KJD" type NVR's with the flip-over E-stop that just presses the stop button. This is because the KEDU E-Stop is a separate switch so can still cut power even if the NVR contacts stick shut. If not using fully qualified industrial safety parts having a second means of stopping is good insurance Robert G8RPI.

I tested by having the drill motor running then switching off the socket on the wall, heard the contactor delatch ?; waited a couple of seconds then switched the power back on, the drill did not start up, I had to push the start button to get it to run, all's well that ends well & with a sigh of relief I hadn't tripped the RCD in the garage.
